Irish budget airline Ryanair plans to offer flights between Europe and the US in four to five years.

Europe’s largest budget carrier said its board had given the green light to develop transatlantic services, connecting airports such as London Stansted and Berlin with New York, Boston and Miami. One-way tickets could cost as little as $15.

"It’s dependent on attaining viable long-haul aircraft and we estimate that’s four to five years away," a Ryanair spokesman told the BBC.
